The full-duplex architecture allows simultaneous transmit and receive on the bus, eliminating the turnaround delay inherent in half-duplex designs. When laying out the bus, the 70 mV of receiver hysteresis provides built-in noise immunity against signal reflections and ground shifts common in industrial cabling — no external filtering needed for most runs under 100 meters at this speed. ## Supply rail and logic-level compatibility This is a 3.3V-only part: the VCC input is not rated for 5V, and the logic-level I/O (driver input, receiver output) expects 3.3V CMOS levels. Do not connect it to a 5V microcontroller UART without a level translator, as the absolute maximum ratings for logic inputs are tied to the supply range. The receiver output is specified for 3.3V logic, so a 5V-tolerant input on the MCU side is not sufficient — the transceiver cannot drive a 5V logic high.","metaTitle":"TI SN65HVD1476DR RS-485/RS-422 Transceiver, 50 Mbps","metaDescription":"Texas Instruments SN65HVD1476DR is a full-duplex RS-485/RS-422 transceiver with 50 Mbps data rate, 70 mV hysteresis, 3V-3.6V supply, -40°C to 125°C range, in","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Full","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS422, RS485","Data Rate":"50Mbps","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65HVD1476","Receiver Hysteresis":"70 mV","Operating Temperature":"-40°C~125°C","Supplier Device Package":"14-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6430","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6a3d6fbce07d753c614ee20fa6ce4e7a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD1476DR/alternatives.json"},"ai":{"faq":[{"question":"What is the SN65HVD1476DR's type and duplex configuration?","answer":"The SN65HVD1476DR is a full-duplex transceiver supporting RS-485 and RS-422 protocols, with one driver and one receiver."},{"question":"Is the SN65HVD1476DR compatible with 5V logic?","answer":"No."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD1476DR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD1476DR when reusing this data.
